Belts and rack and pinions possess a few common benefits for linear movement applications. They’re both well-founded drive mechanisms in linear actuators, providing high-speed travel over extremely long lengths. And both are frequently used in huge gantry systems for material handling, machining, welding and assembly, especially in the auto, machine device, and packaging industries.
Timing belts for linear actuators are usually manufactured from polyurethane reinforced with internal metal or Kevlar cords. The most typical tooth geometry for belts in linear actuators is the AT profile, which has a huge tooth width that provides high resistance against shear forces. On the driven end of the actuator (where in fact the electric motor is attached) a precision-machined toothed pulley engages with the belt, while on the non-driven end, a set pulley simply provides assistance. The non-powered, or idler, pulley is often used for tensioning the belt, although some designs provide tensioning mechanisms on the carriage. The type of belt, tooth profile, and applied pressure power all determine the drive which can be transmitted.
Rack and pinion systems used in linear actuators consist of a rack (generally known as the “linear gear”), a pinion (or “circular equipment”), and a gearbox. The gearbox helps to optimize the acceleration of the servo motor and the inertia match of the system. One’s teeth of a rack and pinion drive could be directly or helical, although helical teeth are often used due to their higher load capacity and quieter operation. For rack and pinion systems, the maximum force which can be transmitted can be largely dependant on the tooth pitch and how big is the pinion.
Our unique knowledge extends from the coupling of linear program components – gearbox, motor, pinion and rack – to outstanding system solutions. We offer linear systems perfectly designed to meet your specific application needs with regards to the smooth running, positioning precision and feed pressure of linear drives.
In the research of the linear motion of the gear drive mechanism, the measuring platform of the gear rack is designed to be able to measure the linear error. using servo motor straight drives the gears on the rack. using servo electric motor directly drives the gear on the rack, and is dependant on the movement control PT point mode to recognize the measurement of the Measuring distance and standby control requirements etc. Along the way of the linear movement of the gear and rack drive mechanism, the measuring data is obtained by using the laser interferometer to measure the placement of the actual movement of the apparatus axis. Using minimal square method to resolve the linear equations of contradiction, and also to extend it to any number of moments and arbitrary amount of fitting features, using MATLAB programming to obtain the actual data curve corresponds with style data curve, and the linear positioning precision and repeatability of gear and rack. This technology could be prolonged to linear measurement and data evaluation of nearly all linear motion mechanism. It can also be used as the basis for the automated compensation algorithm of linear motion control.
